6.3.6.2.2 Spin Turn
Hydrostatic steering gives the operator
significantly more manoeuvrability than
mechanical steering. To make a spin turn, refer
to illustration and proceed as follows:
CAUTION
Be sure area is clear before making turns.
Although windrower pivots "on the spot",
ends of header travel in a large arc.
a. Move the GSL (A) out of N-DETENT towards the
seat and hold.
b. Slowly turn the steering wheel in the desired
direction of turn. The windrower will pivot
between the drive wheels.
c. To stop the turn, slowly turn the steering wheel
back to its centered position.
d. To increase the turn radius, slowly move the
GSL away from neutral. Remember that this will
increase ground speed as well.
e. To stop the turn, move GSL back to neutral, and
return the steering wheel to center.
6.3.6.2.3 Stopping
WARNING
Do not move ground speed lever rapidly
back to neutral. Operator may be thrown
forward by sudden stop. Always wear seat
belt when operating windrower.
a. SLOWLY return the GSL (A) to neutral and into
N-DETENT.
b. Turn steering wheel until it locks.
c. Move throttle lever (D) to low idle position.
NOTE
Avoid unnecessary idling. Stop engine if it
will be idling for longer than 5 minutes.
d. Brakes are automatically engaged when
steering wheel is locked in neutral position.
CAUTION
Park on a flat, level surface, header on the
ground and the ground speed lever in N-
DETENT.
IMPORTANT
Before stopping engine, run at low idle for
approximately five minutes to cool hot
engine parts (and allow turbocharger to
slow down while engine oil pressure is
available).
e. Turn key counter-clockwise to OFF position.
